TYBEWRITING MACHINE,

To all whom it may concern Be it known that I, JosnPH B. HOLDEN,

citizen of the United States, andresident of State of New York, have invented certain new and useful Improvements in Typewriting. Machines, of which the following is a specification. p

My invention relates to typewriting and likemachines, and more particularly to the mounting and guiding parts of the type actions of such machines.

The present invention was devised more particularly for embodiment in the Remington Portable machine, and is intended to improve certain features thereof disclosed for example in the patents to John H. Barr, No. 1,320,034, dated Oct. 28, 1919, and .to Arthur W. Smith, No; 1,342,513, dated June 8,1920, and to'overcome certain disadvantages found in the features in question.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the accompanying description and particularly pointed out in the appendedc-la-ims.

.In the drawings, wherein like reference characters indicate corresponding parts in the different views,

Specification of Letters Patent. Application filed January 25, 1922-. Serial No. 531,649.

Patented Au .'1, 1922.

While I contemplate, in the present instance, embodyin'g myinvention in a light portable ty e'wntlngmachine such as'the emlngtonortable, it should be understood that the invention is available for use,

may be embodied in other styles of machines.

I have shown only so much of the Remington-Portable machine as may .be necessary arrive at an understanding of my nvent on in its inclusion therein. It is desirable in a portable machine to make the parts as light and compact aspossible consistent with the necessa' rigidity and strength required therefor. hen it is feasible to use sheet metal from which to construct-parts of the machine, such course is deemeddesirable, both from the int of viewof lightness ,of construction an reduction in cost of manufacture.

In the resent instance 7 shown, inc uding the'frame, key levers, sublevers, type bars, guide comb for the key levers and the mounting and guide for the sublevers are, made of sheet metal.

The main object of'my present invention 1s to so construct and parts that they shall, in their support one by another, have suflicient rigidity to prevent them from flexing or being sprung apart and thereby prevent other parts from being accidenta-lly disarranged or displaced during the operation of the machine, as will hereinafter more clearly appear.

The machine comp-rises an outer sheet metal frame 1 and an innersheet metal frame 2 detachably secured thereto and supporting various workin parts of the machine. The forward en s of the side plates of the inner supportin frame 2 are united by a sheet metal combined fulcrum plate and guide'comb, indicated as a whole by the reference numeral 3. lnwardly projecting ears 4 are formed on the side plates of the frame 2 and-are tapped to receive headed screws 5 and 6 which connect the member 3 to said frame. -The lower portion of the member 3 is slotted at 7 from its lower ed e to receive key levers 8 and forma i e comb therefor. Above the slots 7, an extending longitudinallyof the member 3, is formed a rib 9 that tends to strengthen the member against lateral deflection or bending. Guide slotslO are formed in the member.3 above the rib 9 and extend down from all' of the partsunite certain of these" the I upper edge thereof. {Such slots ar 'aligned with the slot 7' so that each slot 7 has ably supported as by a fulcrum, on the bottom we 14 of the associate slot 10 in the member 3, as shown. The upper forward edge portion of each sublever 11 is curved at 14 in an are around the bearing 13 of the sublever. This enables the sublever to. oscillate freely on its fulcrum while the sublever by oo-operation with a'keeper, as w ll hereinafter appear, is prevented from being displaced from its fulcrum,

In order to prevent the sublevers from be ing accidentall displaced from their fulcrums I provi e a so-called separately detachable kee er 15. This keeper is preferablymade 0 sheet metal and is substant ally angular in cross section to give added r1g1dity thereto. The member 15 extends transversely of the machine above the member 3 and is provided with downwardly bent ears .16 at the ends thereof. These ears are apertured .to receive the stems of the screws 6 which, with the screws 5, secure the member 3 to the machine frame.

In this manner the members 3 and 15 are "rigidly though detachably connected together at the ends thereof and also are secured to the frame of the machine. The part 15 'of the keeper is preferably curved in cross section to'conform substantially to the curvature of the edges 14' of the sublevers 11 situated directly beneath said part 15. There is preferably, in the normal position of the parts, a bare clearance between each edge 14 and the part15 ofthe keeper, so that any upward displacement of the forward end ofa sublever from its fulcrum brings the edge 14* of the sublever against the keeper and prevents any further movement of the bearing of the sublever away from its fulcrum.

In order that the keeper plate 15 and the combined comb and fulcrum plate 3 may be prevented from being sprung or flexed relatively one to the other, which might result in the sublevers, or some of them, being displaced or disarranged, I provide by m present invention means for firmly thoug detachably connecting the members 3 and 15 together intermediate the ends thereof, as well as at the ends.

I prefer to provide at various lpoints throughout the length of the member 3 up-- are shown connected as they are in the wardly projecting integral connecting lugs 17 that extend through openings in the part 15, each opening conforming in shape to the cross section of a lug received thereln, so as to prevent any relative movement between the members 3 and 15 fore-and-aft of to the width of the lug 18 but is deeper f0reand-aft of the machine than the thickness of said lug. A substantially T-sha ed connecting head, designated as a who e by the reference numeral 20, has a depending stem 21 that passes through the opening 19 from above and is tapped to receive a headed screw 22. The stem of the latter passes from front to rear through an opening 23 in the member 3 and is then threaded into' the tapped opening in the head 20, firmly though detachably connecting said head to the member 3. The depending stem 21 is of a width correspondin to the width of the opening 19, and is 05 a thickness which, with the thickness of the lug 18, fills the depth ofthe opening 19 fore-and-aft of the. machine. When the member 20 is secured in place the cross head or piece 24 thereof, which is of a length that exceeds the width of the opening 19, overlaps and rests on the body portion of the part 15 of the keeper. This detachable interlocking connection between the member 3' and the keeper 15, about midway in the length thereof, positively and effectively ties the two together intermediate their ends so that there can be no movement of one relatively to the other in any direction. The comparatively rigid keeper being thus firmly connected to the member 3 prevents the latter from being flexed or sprung, which springing of the plate 3 would result in a displacement or disengagement of the sublevers 11. The employment of the lugs 17 in the manner described at various points throughout the length of the members 3 and 15, and the screws 6 at the end of said members. further aid in effectively and firmly, though detachably, connecting them together and preventing one part from being sprung or moved relatively to the other when in use at all points lengthwise of said members. The'meansin question nevertheless enable the keeper 15 to be readily detached from the member 3 when desired, thus enabling, a detachment of the sublevers from said member to be readily effected.

For the'purposes of my present invention it is immaterial how the key levers 8 are connected to actuate the sublevers 11 and how the latter are connectedto actuate the type bars. In the present instance said arts emington-Portable machine, and as disclosed in the patents hereinbefore referred to. Thus each key lever 8 is connected by a lllllk 25 to its sublever 11, the latter being connected b a second link 26 to a second SUblBRQQI' 27. Each sublever 27 is fulcrumed intermediate its ends at 28, and is provided at its rear end with segmentall arranged gear teeth 29. These teeth mesh with similar teeth 30 on the heel of the companion'type bar 31, pivoted at 32 to strike downwardly and rear- Wardly against the top of a platen, not shown.

From the foregoing description it will be understood that I have provided simple, inexpensive and effective means for detachably securing the combined comb and fulcrum plate 3 and the keeper 15 together, and for sup orting one by the other to prevent them rom being accidentally sprung apart, and thereby prevent the sublevers '11 from bein accidentally disarranged or get- .tin out 0 .place.

arious changes may be made without departing from my invention.
